I have installed Ubuntu 13.04, but I am facing a problem with the European video settings.
The HD-video (25/50 Hz interlaced) are played back at 60 Hz, giving a non-stable (fluid) video playback, a 10 Hz refresh out of sync.

There are country settings in Ubuntu, shouldn't these be handling the video refresh rate?

Now, I use an Intel 3225 @ shuttle xh61v with the Ivy bridge HD 4000 video refresh settings of 60 Hz (VS),
I like to change this to 50 Hz, 75 Hz or 100 Hz (a multiple of 25 Hz).

Does anybody has an idea how to change this?

For the programmers: Can a configuration setting be integrated in 'about this computer'? And can the refresh rate default to the correct region settings?
